How wemos d1 mini pro flashing with arduino ide?

[klotzma]

Hello everybody, I would like to flash my wemos d1 mini Pro and connect a PZEM004t V3.

So far I have added the PZEM zip under Arduino IDE and now only has to configure the rest with Atom.

Under arduino.h I have to select the hardware now. Which one do I choose for the Wemos D1 mini pro?

I've already tried it with Wemos D1 mini, but then comes at the build always a mistake: Hardware not supported!

"Hardware not supported!" will show if you have not selected any hardware define, like NODEMCU_LOLIN or ITEAD_SONOFF_POW. There is a dummy hw NODEMCU_BASIC that defines bare minimum for things to work: MANUFACTURER and DEVICE. Please reference comments in the header files.

ref platformio.ini: https://github.com/xoseperez/espurna/blob/fbf2b71749307688f7258ad8235bc0f5d068e926/code/platformio.ini#L289 you can add use

#define NODEMCU_BASIC
#define LED1_PIN 2
#define LED1_PIN_INVERSE 1
#define DEBUG_SERIAL_SUPPORT 0
#define PZEM004T_SUPPORT 1

DISABLE_POSTMORTEM_STACKDUMP does nothing in Arduino IDE environment.

Do I have to change something here? https://github.com/xoseperez/espurna/blob/fbf2b71749307688f7258ad8235bc0f5d068e926/code/platformio.ini#L2

So I have to change that? https://github.com/xoseperez/espurna/blob/fbf2b71749307688f7258ad8235bc0f5d068e926/code/espurna/config/hardware.h#L92

that it looks like that:

#elif defined(NODEMCU_BASIC)
    // Info
    // Generic NodeMCU Board without any buttons or relays connected.
    #define MANUFACTURER        "NODEMCU"
    #define DEVICE              "BASIC"
    #define LED1_PIN 2
    #define LED1_PIN_INVERSE 1
    #define DEBUG_SERIAL_SUPPORT 0
    #define PZEM004T_SUPPORT 1

Do I have to flash it with this ZIP?: https://github.com/xoseperez/espurna/tree/fbf2b71749307688f7258ad8235bc0f5d068e926

What do you mean by that?

DISABLE_POSTMORTEM_STACKDUMP does nothing in Arduino IDE environment.

[mcspr]

Right. Now, if you add #define NODEMCU_BASIC line in the arduino.h, it will use those defines. And yes, please do use dev tree to build.

platformio.ini is not used in any way, that was just for reference of how pre-built binary nodemcu-pzem004t.bin is made. DISABLE_POSTMORTEM_STACKDUMP will not have any effect, you can safely ignore it for your builds.

[klotzma]

Which board do I choose then, so I can build the bin?

[mcspr]

You can select either Generic or Wemos D1. Just make sure that the flash size is 4MB if you want to do OTA upgrades

ok. I get this error:

`In file included from sketch\config/all.h:36:0,

Can you help me ?

[klotzma]

I now have a bunch of libraries installed and now comes the error:

`In file included from C:\Users\Benchawan\Downloads\espurna-dev\espurna-dev\code\espurna\ntp.ino:15:0:

sketch\libs/NtpClientWrap.h: In constructor 'NTPClientWrap::NTPClientWrap()':

     udp = new WiFiUDP();

         ^

Please see https://github.com/xoseperez/espurna/wiki/ArduinoIDE#installing-libraries-manually NtpClientLib is a different version from the one in the library manager

I got it now and loaded espurna on the Wemos d1 mini. Thank you for your help!!!
